JOHN MAGEE, OF LAWRENCE, MASSACHUSETTS.

STOVE.

Specification of Letters Patent No. 25,128, dated August 16, 1859.

To all whom it may concern:

Be it known that I, JOHN MAGEE, of Lawrence, in the county of Essex andState of Massachusetts, have invented an Improved Stove; and I do herebydeclare that the same is fully described and represented in thefollowing specification and the accompanying drawings, of which- Figurel, is a side elevation of it. Fig. 2, a vertical and central section ofit. Fig. 3, is a horizontal section taken through the flrepot grate.Fig. 4, is a horizontal section taken through the ash pit and baseflues.

The nature of my invention consists in an arrangement of a pot, grate,hot air chamber, ring ash grate and register and ash pit together andwith direct and descending and base flues as hereinafter described.

In the drawings, A, exhibits a grated fire pot of circular form andbeing composed of a series of bars, a, a, a, &c., arranged at equaldistances apart so as to have spaces between them. These bars extendupward from a horizontal ring grate, B, and terminate at t-heir upperends in a ring or annulus, C, from which a partition ring, D, extends tothe case, E, of the stove, such case being cylindrical and concentricwith the firepot and arranged at such distance therefrom as to form ahot air chamber, F, around it. The lower part of the firepot is providedwith a grate, b. Furthermore, on the ring grate, B, is another grate orregister, G, by which the openings of the grate B, may be more or lessclosed or covered. This register grate turns freely on the fixed grate,which with the fire potgrate is situated directly over the ash pit orchamber H, and open directly out of it.

A flue space, I, partially surrounds the ash chamber, H, and opens intoa discharge flue, K arranged at the back of the stove. Furthermore thesmoke space or chamber, L, over the firepot is provided with a directescape pipe N, and two or any other suit-able number of pipes, M, M,pass and extend downward through the hot air chamber, F, and into theflue space, I. A damper, O, is

placed in the pipe N. The top, P, of the case, E, is applied thereto bymeans of a sand joint, which is composed of a beveled metallic ring R,inserted in the upper part of the case and so formed as to make with thecase, a groove, S, for reception of the ring flange, T, extendingdownward from the top, P, and fitting closely into the case, E. lVhenthe groove is supplied with .sand or its equivalent, and the cover isput in place, the sand will seal the joint so as to prevent the smokeand gaseous products of the stove from escaping through the said joint.

In the operation of this stove', much of the air for supportofcombustion passes through the ring grate, B, and its register, G, andthence between the vertical bars of the frepot and into the fuel thatmay be in such fire-pot. This current of air serves to protect theexternal case of the stove from being burned or becoming too muchheated. The ashes that may drop out of the firepot and upon the ringgrate will pass through the latter into the ash chamber, the amount ofair passing through the ring grate being regulated by its register.

By having the descending pipes M, M, pass through the hot air chamberaround the lire-pot the draft through them will be facilitated andfurthermore by leading the smoke into the base flues, about the ashchamber, the heating powers of the stove are augmented. lVhen the damperis open, the smoke will not pass down through the pipes, M, M, but willescape through the direct flue in which such damper is placed.

I claim* The arrangement of the pot grate, A, the ho-t air chamber, F,t-he ring grate, B, the register, G, and the ash chamber, H, togetherand with direct, descending and base flues substantially as specified.

In testimony whereof I have hereunto set my signature.

JOHN MAGEE.
